Lyn Smith on 20 Oct 14This was a extremely helpful source that explained the differences of the three cortical fibers. Though I knew about the roles that white fibers fulfilled, it was clarifying to read this source on the differences among the specific fibers. The commissural fibers connect the two hemispheres of the brain. Association fibers connect different gyri together. Since gyri gyrate in an up and down fashion, the association fibers create a U-shape, so they are sometimes called U-fibers. Projection fibers connect the cortex to the lower brain and brainstem. This article was extremely helpful, as parts of the basal ganglia and limbic systems had been confusing me. In particular the corpus callosum and fornix in these systems had been confusing me as to what they did. This source explained that they just bus the information, and do not have a complicated internal structure, like many of the nuclei in that region. This really helped me understand these two systems, and the roles that each component plays within them.
